ABSTRACT:
A seat cushion assembly has a lower layer of resilient shape-retaining material with an upper surface having a pair of adjacent parallel channel-shaped recesses extending rearwardly from a front end of the cushion assembly and shaped to conform to the undersides of the thighs of a sitting person. The upper surface also has a rear recess in a rearward and intermediate area positioned to be beneath the buttocks of the sitting person. An insert of relatively firm deformable material is located in the rear recess of the lower layer, and an upper layer of soft material covers the lower layer and the insert. The upper layer has channel-shaped recesses conforming with the channel-shaped recesses in the lower layer and a buttock-receiving recess over the insert. The insert serving to accommodate ischial tuberosities of the sitting person and prevents the ischial tuberosities from bottoming out through the cushion assembly. The insert also provides an even distribution of forces over these bony areas.
